    // Enter amazing code here:
  Game game = new Game("treehouse");
  Prompter prompter = new Prompter(game);
  boolean isHit = prompter.promptForGuess();
  if (isHit) {
    System.out.println("We got a hit.");
  } else {

When you create a Prompter object you can now use the methods in the class. In this case, if you go to the Prompter class definition, you will find the promptForGuess() method that uses the Game object that was used as an argument in the declaration of the Prompter to prompt for a guess. It returns a boolean that will be set to True if the guess hits "treehouse" which was the argument in creating the Game object used in turn in creating the Prompter object.

Basically you are creating a reference variable that points to an object in the heap, and you are basing in the game object as a argument.
